Abstract

PURPOSE:  To evaluate the efficacy of the flexirigid thoracoscope as a tool for the diagnosis in pleural effusions of unknown etiology.

METHODS:  Between May 2002 and October 2004, 19 patients with pleural effusion who had remained undiagnosed even after thoracentesis were performed medical thoracoscopy under local anesthesia using a flexirigid thoracoscope, a rigid thoracoscope with a bidirectional flexible tip. Patients were examined using supplemental oxygen, either in the endoscopy suite, or at the bedside in a general ward after premedicated with an intramuscular injection of hydroxyzine and pentazocine.

RESULTS:  The mean age was 69 years, with a male/female ratio of 5:1. A definitive diagnosis was made in 17 of the 19 patients (89%), 6 malignant pleural mesothelioma, 5 metastatic pleural carcinoma, 4 tuberculous pleurisy, 1 empyema, and 1 uremic pleurisy. The mean examination time was 22 minutes. Complications observed were; 1 case of CO2 narcosis, 1 case of pneumothorax, and 5 cases of subcutaneous emphysema. There were no fatalities.

CONCLUSION:  The flexirigid thoracoscopy under local anesthesia can be considered to be a rapid, easy, less invasive, and moreover an accurate diagnostic procedure.

CLINICAL IMPLICATIONS:  It is expected to become a routine examination for pleural effusion of unknown etiology.
